oracle adf - RichTextEditor adf component ,help needed -

I want to use the adf richtexteditor component and want to work below two things:

1. A letter counter [number of character dynamically enters] 2.spell check

   I am using Jdev version 11.1.1.6.

   You can use the JavaScript, call function, to hook up the JavaScript call in the event. Something like this:

     & lt; Af: resource type = "javascript" & gt; Function doSomething () {} & lt; / Af: Resources & gt; & Lt; AF: richTextEditor & gt; & Lt; Af: clientListener method = "doSomething" type = "press key" / & gt; & Lt; / AF: richTextEditor & gt;
